Abstract

An optical power divider for use with one incoming and a plurality of outgoing glass fibers includes an imaging device arranged on an optical axis between the incoming and outgoing glass fibers. At least one plane binary phase grating is disposed in the pupil of the imaging device. The grating is one-dimensional, has a duty factor of at least substantially 1:1, and has an optical path difference of at least substantially H=0.32 lambda +n lambda or H'=0.5 lambda +n lambda where n=0,1,2 . . . . The end of the incoming glass fiber is coaxial with the optical axis. The outgoing glass fibers are arranged in such a way that they receive the radiation which has been diffracted into the various diffraction orders of the phase grating. lambda is the wavelength of the radiation.
